Binding menu model to a tree component

Hi,
I have generated menu models to all my unbounded task flows in my application and I want to display the menus as a tree in the side bar ...
The hosted demo here tells that we can add the same menu model to a tree component...
http://jdevadf.oracle.com/adf-richclient-demo/faces/components/pagehierarchy/page.jspx?_afrLoop=14156998585414802&_afrWindowMode=0&_afrWindowId=null
Is it possible to bind a menu model to a Tree component? If possible...how to achieve this? If not...Is there any other way we can display the application menu in the form a tree...using the existing menu models?

Hi,
I don't understand your question. You simply can use the tree and specify the MenuModel as its value and define the right detailStamp, like any kind of tree. Or was your question more general like how to use a tree?

Binding 2 Models in the Same component controller

I'm using 2 Import Adaptive RFC Models. I want to bind both the models in the component controller of the same web dynpro component.
But when I try to do model binding for the second model, it does not allow me to do so. If I try to bind the same model in a different project, it happens perfectly and works fine. That means the model i.e. the BAPI is perfectly ok.
Can anyone please tell why is it not allowing to bind 2 models in the component controller of the same web dynpro component?

Hi Satyadev,
   If I undersatand your description properly, you have 2 models nodes in a webdynpro component, and you want to bind these two together. If this is the question, then, yes you cant do the bindings declaralatively, you have to do it dynamically...
Look at the code snippet below, it may help you...
Suppose ChildNode1 and ChildNode2 are the model node in the context of the component controller. Then you can map these two nodes dynamically....
wdContext.wdGetAPI().reset();
     IWDNodeInfo testNodeInfo1 = wdThis.wdGetAPI().getContext().getRootNode().getChildNode("ChildNode1", IWDNode.LEAD_SELECTION).getNodeInfo();
     IWDNodeInfo testNodeInfo2 = wdThis.wdGetAPI().getContext().getRootNode().getChildNode("ChildNode2", IWDNode.LEAD_SELECTION).getNodeInfo();
     testNodeInfo2.setMapping(testNodeInfo1, true);
     testNodeInfo2.addAttributesFromDataNode();
Hope this helps,
Please let me know if I have not understood your question properly...

Bind menu bar to a menu model

Hello,
I'm trying to bind my menu bar (af:menubar) to a menu model.
I created the menu model from my main unbounded task flow (adfc-config.xml) : right click -> "Create ADF Menu Model..." giving me root_menu.xml.
My menu bar is currently defined in a page fragment mainMenu.jsff used in my pages.
According to the 11g r2 documentation it is possible using the value attribute of the menubar component : Working with Navigation Components
But I can't find how to do this in 11g r1 as there is no value attribute...
Any idea ?
I'm using JDeveloper 11.1.1.7.0.
Thanks.
Yann.

So obviously it seems it is not possible ?
I have tried using an iterator to generate menu items in my menu bar (mainMenu.jsff):
<?xml version='1.0' encoding='UTF-8'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"
          xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
<af:menuBar id="mb1" styleClass="mainMenu" stretchId="stretch1">
    <af:iterator var="myMenu" id="i1" value="#{root_menu}" rows="2">
      <af:commandMenuItem text="#{myMenu.label}" id="cmi1" icon="#{myMenu.icon}"
                          action="#{myMenu.doAction}"/>
    </af:iterator>
    <af:spacer id="stretch1" clientComponent="true"/>
</af:menuBar>
</jsp:root>
Here is my menu definition (root_menu.xml):
<?bxml version="1.0" encoding="windows-1252" ?>
<menu xmlns="http://myfaces.apache.org/trinidad/menu">
<itemNode id="itemNode_home"
            label="#{adfBundle['testapp.view.TranslatedText'].MAIN_MENU_HOME}"
            action="menu_home" focusViewId="/home"
            icon="/images/icon_home.png"/>
<itemNode id="itemNode_employees"
            label="#{adfBundle['testapp.view.TranslatedText'].MAIN_MENU_EMPLOYEE_MANAGEMENT}"
            action="menu_employees" focusViewId="/employees"
            icon="/images/icon_user.png"/>
</menu>
My adfc-config.xml :
<?xml version="1.0" encoding="windows-1252" ?>
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">
<view id="home">
    <page>/home.jspx</page>
</view>
<task-flow-call id="tf-employees">
    <task-flow-reference>
      <document>/WEB-INF/tf-employees.xml</document>
      <id>tf-employees</id>
    </task-flow-reference>
</task-flow-call>
<control-flow-rule id="__1">
    <from-activity-id id="__2">*</from-activity-id>
    <control-flow-case id="__4">
      <from-outcome id="__5">menu_home</from-outcome>
      <to-activity-id id="__3">home</to-activity-id>
    </control-flow-case>
    <control-flow-case id="__6">
      <from-outcome id="__8">menu_employees</from-outcome>
      <to-activity-id id="__7">tf-employees</to-activity-id>
    </control-flow-case>
</control-flow-rule>
</adfc-config>
Then I include the menu fragment (mainMenu.jsff) in my pages home.jspx, employees.jspx and editEmployee.jspx.
Menu items are generated correctly (labels, icons) even if I have warnings (reference myMenu.xxx not found) but only the employees menu item from the home page is working... others don't do anything in all pages.
Did I missed something ?
Can anyone test this ?
Thanks.

Tree component menu

Hi guyz,
I’ve developed a menus using
Tree Component with
xml connector. can anybody help me to control its speed,
like in my scenario;
suppose, 3 nodes captioned (item 1 & item 2),
- item 1 has 10 sub items and item 2 option has 5
issue #1: there's no speed synchronization b/w both (item1
& item2). item 1 has take more time to popup then item2 coz of
xml data.
issue #2: I want to increase the speed of popup or scrolling.
Please help me that how can I optimize my menu and resolve
these issues. Please tell me any book, development kit (software),
extensions etc. for reference or help.
Thanks
mail me

JDev10g: Using a Tree component based on different queries.

Hello,
I've been doing some research on how to implement a tree component in ADF which I got working. However I need to implement a tree component that uses several different queries.
The parent node would be one query, the child/leaf nodes would be based on another query but still related to the parent.
For Example: 'select parent_nodes from mydatabase' then 'select child_nodes from mydatabase where child_nodesID = parent_nodesID'
This will ultimately have to branch down more levels but I'm not sure exactly how to achieve this. I'm thinking I have to create new View Objects but I'm not sure exactly how to do that either.
Thank you in advance.

For an SQL query on a database use a View Object. First, you will need to create a new Entity object to represent each table in the database you need to use in the queries. Once you have created your view objects with their correct SQL queries, you need to specify how they are related. Example:
RootView is all elements with ParentId of null.
OtherView is all elements with ParentId not null.
RootToOtherLink is a view link which links RootView.Id to OtherView.ParentId. You can specify this in the dialog. You will want to select all accessors available to make your life easier later, but make sure to name them something you will recognize, like "RootToOtherDestination".
You will also need OtherToOther Link which links OtherView.Id to OtherView.ParentId. This starts the recursive nature of the hierarchical relationship.
Once you have this set up, you will need to create an Application Module so that you have a data control you can bind your tree to. Set up the data model in a hierarchical fashion using your link.
This will create a data control on the Data Controls pane you can drag onto your .jspx page. A menu will show up from which you can select tree component. This will take you to the tree binding dialog. Here is where all your work so far will pay off. You want to click the green plus button to add your RootView. Then, with the RootView selected you will want to hit the green plus again to select your destination accessor, such as "RootToOtherDestination" as mentioned earlier. This will show the OtherView as a child of the RootView. Finally, with OtherView selected you will want to hit the green plus again and select your other destination accessor, such as "OtherToOtherDestination". Select the attributes you want to have available to your tree at the bottom of the dialog and click ok.
Your tree will show up. If you want to customize the way it looks or especially the attributes it displays in a node, those can be edited in the <af:tree> tag on your .jspx page.

How to create dynamic tree component

I am using netbeans 5.5 and visual web pack to develop my jsf application.
I want to add a tree component that will be tied to a table with following columns:
id,parent_id,name
Actually the table stores data in tree structure with parent_id storing the parent of the row.
So a row with parent_id = 0 will be the root nodes of the tree.
When ever any root node is selected i want to fetch its children from the database and populate then as children of that parent node.
The tree can go to any depth so i want to make my tree component dynamic enough to handle this requirement.
How can i accomplish this.
I just want to add listerner for the plus sign of every node so that when the plus sign of that node is clicked i just want to get the id of the corresponding node.

What i'm trying to do is create an organizational structure.
Global>Region>Plant-->Corporation
The output from the RFC is a structure containing every possible combination for orgazational hierarchy. Basically a flat table with record for every possible combinaton of Region-Plant-Corporation. This data needs to be bound to a tree structure so that we can call BW queries based on that level. For example: Give me aged inventory for the SAP corporation within the plant Berlin that is located in the Europe region.
Now that you understand the business reason will the nodes that represent Region and Plant and corporation be non-singleton nodes or recursive? I was thinking a hierarchy of non-singleton nodes.
I can bind these nodes to the Region - Plant - Corporation elements returned from in the flat table structure. I will probably get duplicates as a specific Region will be listed multiple times for every possible combination of the data beneath it. I'm not so concerned about that right now as I want to make sure I understand how in Web Dynpro to bind the data to the tree.
Hopefully this makes some sense. Can you elaborate on how this may be constructed in context of the view?
Would i create a model node for region (0..n), model node for plant (0..n), and a model node for Corporation (0..n)?
Or does this sound totally incorrect?
julian
We have 3 regions over 50 plants and probably around 500 corporations.

Hi,
I don't have a testcase, so just guessing
1. Did you check if the root menu item is listed as a page in teh ADF Security editor? Chances may be you don't have permission to access it
2. You use visible and rendered properties, which is not needed. If you choose rendered then the menu item is not rendered if you don't have access privileges. This also means that it cannot be PPR'ed for conditional show/hide. Using visible and set it to false based on the permission will hide the component but keep it as part of the JSF component tree. In your case visible has no effect because you set rendered to true/false

Custom icon per entry in the AS2 Tree Component (using CS3)

I have a tree component that loads its data from an XML file and I wonder if I can customize every entry to have its own icon by adding an icon attribute to every entry in the XML and giving the tree an action to read that icon (which would exist in the library of the Flash file). My goal is to reproduce a tree within an application that my company is developing (it's for a training tool related to that application).
My XML says something like <node label = 'Label' heading = 'LABEL' desc = 'Description' icon = 'icon1' />
My label is what the tree displays, the heading is what the information dialog in the training tool displays as a title bar, the desc is what the training tool displays within the body of the text for the function description and the icon is what I want to be a reference to the graphic in the library to place as an icon in front of the item rather than use setStyle with the properties for disclosure, leaf, and folder icons.
Is that possible? I haven't found a solution for it yet.

I've never used the Tree component, so I'm just guessing here....
There is a slight delay before the xml file loads and your tree has its data provider.
Perhaps during that time there is no node at mTree.getTreeNodeAt(0) to open? Try adding this just before the last line of your code:
trace("the node is: "+mTree.getTreeNodeAt(0));
What do you get?
You might need to move that code inside the xml's load event handler.
Another thing is that the Flash components tend to work on an invalidate-then-wait-one-frame-to-redraw kind of model. So it is possible you will need to wait one frame after the xml has loaded and then tell it to open that node.
The doLater method might help with that.
var home:MovieClip=this;
var xmlTreeData:XML = new XML();
xmlTreeData.onLoad = function() {
mTree.dataProvider = this.firstChild;
mTree.doLater(home,"delay");
xmlTreeData.ignoreWhite = true;
xmlTreeData.load("xml/treeValues1.xml");
mTree.setStyle("fontSize","11");
mTree.setStyle("selectionColor","0xE0E0E0");
mTree.setStyle("useRollOver",false);

How to use a menu model with a dynamic region and a task flow parameter

I am using JDeveloper/ADF 11.1.2.1
I have a menu model that changes which task flow is displayed in a given dynamic region using a backing bean. That works fine. I would like to be able to pass parameters to that task flow based on which menu item is clicked. For example: i have a task flow which shows a page where input fields are used to filter a table. Depending on the value of the task flow parameter I want to change which input fields are displayed. So i will have multiple menu items which refer to the same task flow but have a different set of parameters. I have tried using request scope variables and setting them in the backing bean for the dynamic region which works until the query is submitted at which point the request scope has changed and the value is no longer available. I have tried a number of other 'creative' approaches but have not gotten anything to work. Anyone done this before? Or have an idea on how to solve it?

Frank,
I did a fair bit of digging based on your suggestions and some things I found in your Oracle Fusion Developer's Guide book and I came up with something that works really well. It is fairly elegant but requires code. It would be nice if something like a setPropertyListener could be rolled into the menu model. That would make my solution completely declarative.
Here is my solution:
My task flow requires a the value #{pageFlowScope.type} to be set. My application has a dynamic region that is changed on the fly using a menu model. The region uses a backing bean (mainRegionManagerBean) which is in the viewScope to manage what taskflow is shown in the region. There are multiple menu items in the menu model that point to the same task flow but pass different values to the #{pageFlowScope.type} parameter. So i wired the menu items up to different methods in the mainRegionManagerBean which set the value for me. See the relevant code below.
I would be very interested in the feedback from someone with more experience than I on my solution. Maybe there is a more elegant way...
In the backing bean there is a primary method that was created by generating a dynamic region link which sets the task flow id and then other methods which call it and set the relevant parameters. (JSFUtils is a helper class i wrote to centralize some common tasks):
public String shipmentTraceMasterTaskflow()
taskFlowId = "/WEB-INF/taskflow/master/shipmentTraceMasterTaskflow.xml#shipmentTraceMasterTaskflow";
JSFUtils.setValue("pageFlowScope.type", "");
return null;
public String shipmentTraceProNumber()
shipmentTraceMasterTaskflow();
JSFUtils.setValue("pageFlowScope.type", "pronumber");
return null;
public String shipmentTraceBOLNumber()
shipmentTraceMasterTaskflow();
JSFUtils.setValue("pageFlowScope.type", "bolnumber");
return null;
In the menu model (notice that these reference the different methods from above):
<itemNode id="itemNode_ProNumberTrace" label="ProNumber Trace" action="#{viewScope.mainRegionManagerBean.shipmentTraceProNumber}" focusViewId=""/>
<itemNode id="itemNode_BOLNumberTrace" label="BOL Number Trace" action="#{viewScope.mainRegionManagerBean.shipmentTraceBOLNumber}" focusViewId=""/>
On the page:
<af:region value="#{bindings.dynamicRegion1.regionModel}" id="r1"/>
In the pagedef:
<taskFlow id="dynamicRegion1" taskFlowId="${viewScope.mainRegionManagerBean.dynamicTaskFlowId}" activation="deferred" xmlns="http://xmlns.oracle.com/adf/controller/binding" Refresh="ifNeeded">
<parameters>
<parameter id="type" value="#{pageFlowScope.type}"/>
</parameters>
</taskFlow>

Questions about AS2 Tree Component (Flash CS3)

I have Flash application with a Tree component on the Stage. I'm using an XML file to create the structure of the Tree component.
Each entry on my XML has the attributes id, label, heading, desc, and icon.
My problem is that I can't seem to be able to set the Tree to default with the first node open.
My code is:
var xmlTreeData:XML = new XML();
xmlTreeData.onLoad = function() {
mTree.dataProvider = this.firstChild;
xmlTreeData.ignoreWhite = true;
xmlTreeData.load("xml/treeValues1.xml");
mTree.setStyle("fontSize","11");
mTree.setStyle("selectionColor","0xE0E0E0");
mTree.setStyle("useRollOver",false);
mTree.setIsOpen(mTree.getTreeNodeAt(0), true);
My tree populates fine, and the handler I retrieve whatever item is clicked works great. However, the tree refuses to default to having that first node open.
I'm also interested in placing custom icons into certain nodes via the icon attribute I've set in the XML, but that will have to come later I guess.

I've never used the Tree component, so I'm just guessing here....
There is a slight delay before the xml file loads and your tree has its data provider.
Perhaps during that time there is no node at mTree.getTreeNodeAt(0) to open? Try adding this just before the last line of your code:

Thinks

Sans,
I am no Apex expert, but with a situation as "complex" as yours, have you thought about creating a VIEW that joins these 7/8 tables, placing an INSTEAD OF trigger on that view to do all the business logic in the database, and base your application on the view?
This is the "thick-database" approach that has been gaining momentum of late. The idea is to put your business logic in the database wherever possible, and let the application (Form, Apex, J2EE, whatever) concentrate on UI issues,

Tree Component as swf

I have a swf file that is a Tree Component... (So when it
diplays it looks like a Directory structure with folders and files)
Some nodes access url links... And some access .doc files on
the network... This works fine when I run it from my local site,
but when I run it on the remote site (Intranet server) the nodes
that reference file paths so nothing, instead of opening the file,
the url type links do work fine on the remote site.
Any thoughts on why this might be occurring ? I am putting
the swf and the associated xml file and html page on the remote
site... Am I missing a file or setting on the server that I have
locally? I am also including my .as file and xml file for review.
Any help would be greatly appeciated.

It is quite a pain in the rear to skin the AS2 components.
And I don't know of many 3rd party components for AS2. I know of
plenty AS3 3rd party components, but if you were using AS3
components you wouldn't need a Tree to replicate the adobe video
workshop type navigation, all you would need is the built in List
component. If you can go sans icons, I would suggest using the AS2
List to get the feel you're looking for.

Tree component - can I declaratively hide the disclosure icon

I have just started working with the tree component. Within the data model that I am working with, I've got branches that may or may not contain children. The child nodes are lazily fetched (which is good, for performance), but this results in the tree not knowing if children exist until the disclosure icon (the arrow) is clicked. This means that when the branch contains no children, the user has to click the arrow, and the arrow just disappears without anything on the tree changing. Because of the nature of the legacy data model that I am working with, I actually have an attribute that indicates if children exist (and I could have created a formula based attribute if no such indicator existed in the data model). I would like to be able to check this attribute (via EL or some other method) and suppress the disclosure icon if no children exist, but I have not found a way of doing it. Is this possible?

I was able to get this to work using the following disclosure listener:
public void testDisclosureListener(RowDisclosureEvent rowDisclosureEvent) {
    Object rowKey = null;
    FacesCtrlHierNodeBinding rowData = null;
    RichTree tree = (RichTree)rowDisclosureEvent.getSource();
    RowKeySet rks = rowDisclosureEvent.getAddedSet();
    if (rks != null && rks.size() == 1) {
       rowKey = rks.iterator().next();
       tree.setRowKey(rowKey);
       rowData = (FacesCtrlHierNodeBinding)tree.getRowData();
       if ( rowData != null && rowData.getChildren() != null ) {
